Move pochhammer to SpecialFunctions.jl? #14

Closed dlfivefifty closed 7 years ago

The Lambda function could be moved at the same time.

There's also the sine and cosine integrals here https://github.com/MikaelSlevinsky/SincFun.jl/blob/master/src/sinc.jl

I don't think Lambda is standard enough

If people need a specialized Pochhammer symbol, then they should be using a ratio of Stirling's approximations. I have this implemented and have used it successfully on a case-by-case basis, cancelling common terms for best accuracy and efficiency.
